Just got my arduino version downloaded and installed to give it a whirl and have afew questions. I do alot of avr stuff on a breadboard and no not actually own an official arduino board (i have my own boards fabed ) and have some technical questions to ask:

* What are the memory requirements for the bootloader and firmware? I noticed that you use the arduino bootloader, but robotC also adds firmware to the memory space. How much space total would that require? I have alot of atmega168's lying around and was wondering if that would ever be possible.

* How exactly does robotC know what serial port the arduino is on? I noticed it does an autodetect for the board. Will robotC be able to find microcontrolers on a breadboard that communicate with a external usb to com port setup?

I believe it is around the 24K mark or so; the 168 is out.

Windows doesn't treat devices on a hub any differently than connected directly. As for auto-detecting, it resets the port and checks for a signature from the bootloader, afaik. This is how it can tell. I also think you can actually specify the COM port to use but that doesn't work flawlessly with the Uno yet.
